FIELD: petrochemical process catalysts.
SUBSTANCE: preparation of catalyst comprises two-step impregnation of preliminarily calcined carrier with first ammonium heptamolybdate solution and then, after intermediate heat treatment at 100-200°C, with cobalt and/or nickel nitrate solution followed by final heat treatment including drying at 100-200°C and calcination at 400-650°C. Catalyst contains 3.0-25.0% MoO3, 1.0-8.0% CoO and/or NiO on carrier: alumina, silica, or titanium oxide.
EFFECT: enhanced hydrodesulfurization and hydrogenation activities allowing involvement of feedstock with high contents of sulfur and unsaturated hydrocarbons, in particular in production of environmentally acceptable motor fuels.
